Insights proposed index wrong SQL statement

[gerwim]

Describe the problem

Creating an index fails:

The error (from network tab):

{"error":{"code":"42601","message":"parsing statement 1: at or near \"_\": syntax error","detail":"source SQL:\nCREATE INDEX IF NOT EXISTS \"offers\"_\"startdate\"_storing_rec_idx ON whatsuper_tst.\"Offers\".\"Offers\" (\"StartDate\") STORING (\"Name\", \"SubcategoryId\", \"SupermarketId\", \"PriceShort\", \"PriceOld\", \"PriceLabel\", \"PriceUnit\", \"ExtraText\", \"ImageUrl\", \"ImageUrlOriginal\", \"EndDate\", \"MetadataId\", \"NeedsReview\", \"Hidden\", \"ScraperRunId\")\n                                   ^\n--\nCREATE INDEX IF NOT EXISTS \"offers\"_\"startdate\"_storing_rec_idx ON whatsuper_tst.\"Offers\".\"Offers\" (\"StartDate\") STORING (\"Name\", \"SubcategoryId\", \"SupermarketId\", \"PriceShort\", \"PriceOld\", \"PriceLabel\", \"PriceUnit\", \"ExtraText\", \"ImageUrl\", \"ImageUrlOriginal\", \"EndDate\", \"MetadataId\", \"NeedsReview\", \"Hidden\", \"ScraperRunId\")","hint":"try \\h CREATE INDEX","severity":"ERROR","source":{"file":"lexer.go","line":404,"function":"Error"}}}

To Reproduce

This happens when applying a suggested index.

If possible, provide steps to reproduce the behavior:

1. Go to insights
2. Go to schema insights
3. filter on insight typoe "create index"
4. Click "create index"

Expected behavior The index is created

Additional data / screenshots Replace index is broken too, but I'm not sure if it's related (didn't look into it, but I assume it is).

Generated SQL:

CREATE INDEX IF NOT EXISTS "offers"_"startdate"_storing_rec_idx ON whatsuper_tst."Offers"."Offers" ("StartDate") STORING ("Name", "SubcategoryId", "SupermarketId", "PriceShort", "PriceOld", "PriceLabel", "PriceUnit", "ExtraText", "ImageUrl", "ImageUrlOriginal", "EndDate", "MetadataId", "NeedsReview", "Hidden", "ScraperRunId"); 

The issue is caused by the double quotes around offers and startdate. This is a valid SQL statement:

CREATE INDEX IF NOT EXISTS offers_startdate_storing_rec_idx ON whatsuper_tst."Offers"."Offers" ("StartDate") STORING ("Name", "SubcategoryId", "SupermarketId", "PriceShort", "PriceOld", "PriceLabel", "PriceUnit", "ExtraText", "ImageUrl", "ImageUrlOriginal", "EndDate", "MetadataId", "NeedsReview", "Hidden", "ScraperRunId");

Environment:

• CockroachDB version: v23.2.1
• Server OS: Debian 12, running the docker container cockroachdb/cockroach:v23.2.1
• Client app: dashboard

Some additional context:

1. It appears that part of index creation statement is built on FE: https://github.com/cockroachdb/cockroach/blob/178be57bb7a77af0cb87932a9a63c6eec424ed62/pkg/ui/workspaces/cluster-ui/src/insights/indexActionBtn.tsx#L215-L227
2. Index recommendation from crdb_internal.cluster_execution_insights suggests an index name with . (dots) which is not allowed if not wrapped with quotes.
3. Could reproduce similar issue when suggested index should be created on table with name like "t2.1"

Assume that logic on UI should be reduced to consume CREATE INDEX... query as is from the server.
